What pickup lines do you use to start a conversation with someone you are attracted to?
I think I use situations to start conversations...
If I'm approaching a female, I'd start by introducing myself, and following up with a compliment of why I had to introduce my self.
How do they typically respond?
If she is interested, she would ask questions, or make small talk while giving off some type of body language.
If she is not interested, she listens to whatever I say, and tells me something like she really into someone right now, but she appreciates the approach.
